測試代碼：

package unicode;import org.apache.commons.lang3.StringUtils;public class ChineseTest {public static void main(String[] args) {ChineseTest tool = new ChineseTest();System.out.println(tool.containsChineseCharacter("Helloab!?12D#asDSF!&#$"));System.out.println(tool.containsChineseCharacter("你好 "));}protected boolean containsChineseCharacter(final String s){if (StringUtils.isNotEmpty(s)){for (int i = 0; i < s.length();){final int codepoint = s.codePointAt(i);System.out.println("Code Point: " + codepoint);i += Character.charCount(codepoint);System.out.println("i: " + i + " CharCount: " + Character.charCount(codepoint));if (Character.UnicodeScript.of(codepoint) == Character.UnicodeScript.HAN){return true;}}}return false;}}

輸出：
